热轧圆钢漏磁检验结果准确性分析

ACCURACY ANALYSIS OF MAGNETIC FLUX LEAKAGE TESTING OF HOT-ROLLED BAR

莱钢引进了先进的矫直、抛丸、探伤设备,对产品质量提供了有力保证,但设备仪器的操作有待标准化。本文通过对分析尺寸、弯曲度和设备相关参数的设定对探伤数据的影响进行分析,找出了影响因素,确定了关键质量控制点,促进了操作标准化,提高了检验准确度。

With the introduction of advanced straightening, blasting and inspection equipments, the product quality assurance capacity in Laisteel increases. However, there are some problems with the op- eration and using of equipments. Therefore, the author does an in-depth exploration Aiming at these problems. Through analyzing the influence on detection data by setting the size, bending and device pa- rameters, this article discovers influence factors, identifies the key quality control points and standardizes the method of operation, and improves the operation standard and the test accuracy.
